Description
Technical field
The present invention relates to a kind of charging station load adjustment methods suitable for garden distribution.
Background technique
It is several that the charging equipment of existing electric car is divided into alternating-current charging pile, direct-current charging post, DC charging heap etc..Nothing
By be it is any, sufficient power supply is all relied on using operation.The principle that Fig. 1 shows existing charging station system is shown
It is intended to, as shown in Figure 1, having several charging piles or several charging heaps, charging pile or charging heap in existing charging station
Generally all by swipe the card or application program of mobile phone open use.Charging station is additionally provided with a charging equipment background monitoring system 100,
Realize operating status management, the disbursement and sattlement etc. to charging equipment.Charging equipment (stake or heap) in standing can be by remotely leading to
Believe that interface (such as Ethernet interface) realizes the data interaction with charging equipment background monitoring system 100.In charging, alternating-current charging pile
Rated power is informed into electric car by CP signal, according to relevant criterion, electric car is in charging pile maximum supply current, vehicle
Carry and compare between the specified input current of charger and charging gun cable rated capacity three, choose wherein minimum value as vehicle-mounted charge
The current maximum allowable input current of machine；And direct-current charging post is then by CAN bus, with vehicle-mounted BMS(battery management system) association
Peak power output is informed vehicle by quotient, one side direct-current charging post, and maximum also can be born electric current and inform direct-current charging post by vehicle, two
Person negotiates after shaking hands, and direct-current charging post is started to charge with a suitable starting voltage and electric current；The heap that charges is generally straight at present
Stream output, is a kind of version of direct-current charging post, in order to which intensive construction simultaneously realizes that multiple gun exports.
The distribution capacity as required for the construction of charging station require it is general all very high, when thering are several to fill in a garden
When power station, the capacity of garden power grid can objectively be caused stress.For example, the charging station planning in a garden has 5
40KW alternating-current charging pile, 3 120KW direct-current charging posts, then before construction, related construction unit just needs to coordinate garden to be provided to
The distribution capacity of few 500KW comes out to be used for charging station.In terms of garden 2000KVA distribution capacity, charging station will need to occupy total
Distribution capacity 25%, and according to " power engineering design manual ", rate of load condensate (the calculated load capacity/transformer capacity * of transformer
100%) safety value generally takes 85%, and practical peak load rate in the case where considering economy and safety conditions generally 60 ~
Between 70%, as described above, if being superimposed the occupied matched transformer capacitance of charging station on this basis, it is very possible super
The safe load rate of transformer out, i.e., practical power load are more than the safe load that transformer can bear, and cause transformer mistake
Heat, voltage fluctuation not only influence charging station and operate normally, and also the normal production to enterprise in garden makes a big impact.
